Applicationfiled. December 2, 1907. Serial No. 40%,"758.

To all whom it may concern:

Be itknown that we, ALBERT DElVlARQUIS and EUGENE CERIAT, citizens ofSwitzerland, residing at San Francisco, in the county of San Franciscoand State of California, have invented a new and useful Fireproof WValland Ceiling, of which the following is a specification in such full andclear terms as will enable those skilled in the art to construct and usethe same.

The object 'o'fthis invention is to make a wall that will take theplaster of the finish directly, and which will not be liable to bethrown down by violent shocks to the build- Another feature of thebuilding construction is to produce abrickceiling'that will be securelyfastened to the joists of the floor above, and which may be appliedeither to the common wooden joists or to the channel iron joists used insteel buildings.

A further object of the invention is to produce a wall that will havedeadening means between the wall proper and the bricks of the wall andthe joists, said means also acting as spacing means for the insertion ofthe as, water, and other pipes and wires place in the modern buildingwithout cutting or in any way interfering with the structural parts ofthe floor.

Another object of the invention is to make a brick that will bespecially ada ted for the work to be done and which will e easilysecured to the joists by means of wires.

Another object of the invention is to produce a brick that will be aslight as is consistent with the work to be done in order that there maybe no danger of the excessive weight making the supporting wires losethe individual bricks.

' In the drawings, in which the same numeral is applied to the sameparts through out, Figure 1 is a perspective view of the system as usedfor a ceiling and floor, two classes of joists being shown, Fig. 2 is avertical sectional view of the ceiling, Fig. 3 is a erspective view ofone of the bricks, and Fig. 4 shows a section through another form ofbrick.

In general our invention consists in providing a woven wire fabric ofexceedingly large mesh, every aperture whereof shall be of the size of abrick, and in roviding in combination with said fabric a brick having agroove around all its four edges whereon rests the fourwires limitingsaid aperture,

said fabric being secured and suspended as detailed below.

The wire fabricis prepared for the ceiling, which we will describefirst, by running steel wires of suit-a'blesize horizontally and parallel from end to end of a room, and securing their end to. any suitable)art o-fthe supporting skeleton of the buil ing in anysuitable way. Suchwires are shown at 1, Figs. 1 and 2. The bricks 2 are made to engagesaid wires along their opposite edges by means of the grooves 3. As each'brickis put inplace, cross wires 4 of galvanizediron are twisted andsecured to said steel wires, said cross wiresbeing caused to engage thegrooves 5 in the transverse ends of thebricks. The fabbr-ic thus formedis supported, where the girders are of woodby mean's'of the suspendingwires 6 secured to the girders by staples 7; and from steel girders bthe hooks 8.

By the above-describe construction we are enabled to provide our novelsound deadening means between the ceiling and the parts above. Thesemeans consist of the air space left between the top of the ceiling asdescribed and the parts above the same, the suspending wires 6, and thehooks 8 being arranged, if desired, to keep said ceil ing out ofimmediate contact with the girders. Note Fig. 2 where such a space isshown below the girder. We purpose also to increase the deadeningeffectby means of a layer of sand strewn on the upper surface of said ceiling.Moreover by providing the space described we leave room for the passageof electric wires, gas, water and other pipes placed in modernbuildings, and for ventilating pipes and fines.

When the space above the room is covered by the bricks reinforced. andsustained in the way described, the edges thereof are sealed withPortland cement.

The floors are similarly constructed of wire fabric and grooved bricks.They are secured to wooden joists by means of staples as shown at 9 Fig.1, and to steel beams by hooks as shown at 10, and their adjoining edgessealed with Portland cement. Outer are made of any suitablesize, andconsist of a square or oblong body of suitable thickness having a grooverunning completely around their four edges. To lighten the Weightthereof it is hollowed out as in Fig. 3 or oth- %rwise cut away as bythe holes shown in Having described our invention what we claim as newand desire to secure by Letters Patent of the United States is asfollows, modifications within the scope of the claims being reserved:

1. In a fireproof Wall, ceiling, and the like, a structural wall member,a plurality of bricks arranged to form a flat surface, every brickhaving a channel all around its edges, a series of parallel wiressecured to the wall member, and passing through the channels in the sideedges of every brick and twisted wires connecting adjacent parallelwires through the end channels of every brick and having their endssecured together around said parallel Wires.

2. In a fireproof wall, ceiling, and the like, a structural wall member,a plurality of bricks arranged to form a flat surface, every brickhaving a channel all around its edges, a series of parallel wiressecured to the wall member and passing throughfthechannels on the sidesof every brick, supporting Wires attached to the beams and parallelwires, P. and twisted wires passing around one of the parallel wires andtied around an adjacent parallel wire for securing the ends of everybrick.

3. In a ceiling wall and the like, a struc- 3 tural wall member, aseries of parallel wires secured to said member by means of twistedwires, a second series of twisted wires secured to one of the parallelwires near the middle of said twisted wire and having its ends twistedtogether aroLmd an adjacent parallel wire, and a plurality of bricksprovided with channels on all their edges and having the parallel wiresand twisted wires lying in said channels.

In testimony whereof we have set our hands this 25th day of November A.D. 1907, in the presence of the two subscribed witnesses.
